Wireless Wide Area Networking
•The next horizon for wireless connections is being able
to access the Internet on a
PDA, wireless phone, or notebook computer
from anywhere in the world without a wired connection.
•
•A WLAN provides a
wireless connection to a network, but devices must be within the stated boundary of the
WLAN.
•
•In 2.5G and 3G wireless systems, wireless wide area networking (WWAN) makes it possible to access the Internet from anywhere within the boundaries of the wireless
network to which you are connected.
